For years, I used a Gillette Sensor cartridge razor, at a cost approaching $2 per cartridge. Now I use a
Merkur 34C safety razor, and after trying at least 20 brands of blade, have settled on
Timor Solingen blades, which cost about $0.50 each. Of course, as I now change blades twice a week instead of once a week and use good shaving soap or cream with a badger-hair brush, I am not sure that I am saving any money, even over the long run. But I am producing much less garbage.
Straight razors scare the crap out of me. Every time I see one, I think of
Sweeney Todd, and of a movie I saw in which I guy starts slicing himself up with one. I don't think I could bear even to have one in the house, much less use one for shaving.
